need help live video streaming

Hello, I work for a public access station that is trying to get the station live on the internet, real (or as close as possible to) real time. I am just trying to figure out the process and am hoping that the holes can be filled in on this thread:

We would be sending the video from a vcr to a video card that can digitize and encode the media into appropriate formats. the confusion is how to embed the mpeg into html and whether you can send it to the server and have it webcasted real time, or close to it.
